My low coolant light comes on a few minutes after I start driving. on 2002 Saturn LW300

I have checked the coolant level and it is normal both when engine is warm and when it is cold. The engine temp guage always remains the same. Any suggestions?

Thanks. I have been looking for a replacement sensor for the coolant level and cannot find one. Will I need to buy a whole new overflow tank? I would rather replace it, but cant find the sensor listed with any parts stores. Any suggestions?

The aftermarket parts comanys do not make that part. It would need to come from the dealer. It should be checked first to make sure that is truly the problem.
